Chickens should pay attention to the identification of these respiratory diseases
No matter which respiratory disease occurs, it is difficult to determine which respiratory disease occurs from the clinical symptoms and the performance of chickens, which brings some difficulties to the diagnosis. In order to help you make a preliminary diagnosis on the spot, various respiratory diseases and common diseases with symptoms of respiratory diseases are introduced as follows:
Chronic respiratory diseases in chickens
The disease is a respiratory disease caused by Mycoplasma gallisepticum. Mycoplasma is widely found in chickens. It can be said that in all kinds of commercial laying hens, a certain proportion of chickens carry this pathogen. However, under normal circumstances, when no other diseases occur, this mycoplasma will not cause disease in chickens. Therefore, mycoplasma can cause chicken disease, must have certain conditions, or must be under the action of a variety of stress factors, can occur.
Infectious bronchitis
The disease can occur in chickens of all ages, but it occurs more frequently in chicks and adult chickens. The disease is caused by a virus. It is characterized by acute onset and rapid spread. There are three types of this disease, namely, respiratory type, kidney type and glandular stomach type.
Chicken infectious rhinitis
It is a disease caused by a bacterium called Haemophilus parachuis. Chickens of any age can occur, but breeding chickens and laying hens are common. The disease is easy to occur in cold seasons. Once it happens and spreads quickly, the whole group can be involved in a few days. None of the chickens of the right age in a chicken farm were spared. Diseased chickens have secretions in the nasal cavity, which are common to flick the nose.
Chicken Newcastle disease
Although the disease is not a respiratory disease, but the occurrence of Newcastle disease is more common, especially the occurrence of atypical Newcastle disease, with obvious respiratory symptoms. At this time, if Newcastle disease is misdiagnosed as other respiratory diseases (such things often occur in actual production), it will cause great losses. Therefore, when chickens have respiratory symptoms, the idea of diagnosis should be to consider whether it is other respiratory diseases after the exclusion of Newcastle disease.

Prevention and treatment of calf forestomach relaxation
Forestomach bradycardia is a disease caused by decreased excitability and contractility of forestomach nerves, and feed can not be digested and moved backward in the forestomach, so fermentation spoilage produces toxic substances, causing digestive disorders and systemic disorders. 1. The cause. Mainly due to too much concentrate and insufficient roughage; feed single or excessive feeding of coarse fodder rich in crude fiber, indigestible straw, withered hay, bran and other coarse fodder; long-term over-feeding of grass powder, cooked into paste root and dregs feed, make the ruminant function.

There is a simple way to castrate a rooster.
One is broiling castrated chicken. First, Baoding, pull out the feathers around the glandular fat hole, cut the protruding parts of adenyl ester flat with scissors, and then apply thermal stimulation to the quasi-adenyl ester point with ignited incense or red-hot round wire, the stimulation method is rhythmic intermittent stimulation, that is, stimulation, immediately leave, and then leave, so repeated, until the abdominal fat hole does not bleed, there is scorched skin. The other is castration with traditional Chinese medicine. Feed the rooster with Schisandra chinensis and white pepper. Weight 5
